Outdoor recreation retail chain Gander Mountain is the latest brick-and-mortar store to suffer from the surge in online shopping. Saint Paul-based Gander Mountain, Inc. announced it was closing 32 stores after filing for Chapter 11 bankruptcy in March.

"Like many retailers, Gander Mountain experienced challenging traffic patterns and shifts in consumer demand resulting from increased direct-to-customer sales by key vendors and accelerated growth of e-commerce," the company said in a statement. "Despite aggressive actions to improve the efficiency of the company's retail operations and support functions, the underlying financial impact from underperforming stores and unproductive, excess inventory hampered efforts to create a sustainable path forward."

2017 hasn't been a great year for retailers. Eighty percent of Americans are now shopping online, leaving brick-and-mortar stores struggling to keep up. That's roughly 251 million people, a huge jump from just 16 years ago, when only 22 percent of Americans shopped on the web.
